Leukocytes adherence receptors are the basis of cells interactions1. Flow cytometry (FCM) makes it possible to assess a characterization of the activation level of a given cellular population by receptor quantifying2. That technique, however does not integrate at the same time, all others factors of leucocyte adhesive phenotype regulation, as spatial distribution and molecular conformation. Our study consisted in exploring the main adhesion receptors (CD62L, CDllb/CD18) on the surface of Polymorphonuclear Neutrophils (PMN) that were prepared under identical conditions and simultaneously analyzed by FCM and Conventional Optical Scanning Microscopy/Deconvolution3 (COSM). Methods: PMN cells from whole blood were obtained using Polymorphprep™. Isolated PMN (105 cells /ml) were incubated with Tumor Necrosis Factor (TNFα, 100 UI/ml) at 37°C for one hour. Quantification of cell surface molecules was assessed according to the quantitative indirect immunofluorescence3 method using QIFIKIT® (Dako, France).
